FIG. 3 is a cross-sectional view taken on line 3--3 of FIG. 2;

FIG. 4 is a perspective view taken from the top, right side and rear of a second embodiment of my new design, of which the top view is essentially the same as FIG. 2 albeit the sink is less deep; and,

In the preferred embodiment, the bottom is plain and unornamented except for the drain opening, which is located as shown in the drawings.
